ATI TEAS 6 PREP 2022: SCIENCE 53 QUESTIONS WITH 100% CORRECT ANSWERS Which of the following is a vitamin that a person's body synthesizes? A. Vitamin E B. Vitamin C C. Vitamin A D. Vitamin D - D... . Vitamin D Vitamin D is the only vitamin the human body synthesizes, and the process of synthesis takes place within the person's skin. At the time this vitamin is inactive, and what makes the process successful is the presence of sunlight. Trypsinogen is one enzyme that the pancreas secretes, and is then converted to trypsin by another enzyme, ___________, within a peron's duodenum. A. Hydrochloric acid B. Pepsin C. Protease D. Enterokinase - D. Enterokinase This enyzme, also known as "enteropeptidase," is responsible for converting this trypsinogen that is not yet active to its active form, which is trypsin. Enterokinase is produced by the duodenum's lining. Hydrochloric acid, pepsin, and protease are all incorrect answers. _________ is/ are responsible for the production of the follicle-stimulating hormone, which enables ovary follicles to mature. A. The ovaries B. The corpus luteum C. The pituitary gland's posterior lobeD. The pituitary gland's anterior lobe - D. The pituitary gland's anterior lobe The pituitary gland's anterior lobe, situated right at the bottom part of the brain, supplies the FSH, which then enters the bloodstream and penetrates the ovaries, causing follicles to mature. When a chemical reaction is taking place, as illustrated here, what does X represent? Sulfuric acid + X = salt + water + carbon dioxide A. Potassium B. Copper (II) oxide C. Sodium carbonate D. Magnesium hydroxide - C. Sodium carbonate Acids are known to react when mixed with carbonates and they end up producing salt and water as well as carbon dioxide. Considering there is a production of carbon dioxide during the reaction, it means that the substance 'X' represents can only be a carbonate. The other choices have no carbonate. There is a ball tied to a pole using a rope, and it is making a circular movement at a speed that is constant. Which of the following statements is true regarding the ball? A. No acceleration is involved B. The force is moving away from the circle's middle C. The force is moving toward the circle's middle D. The force is moving at a circle's tangent - C. The force is moving toward the circle's middle The present centripetal force happens to be directed at the circle's center. If the velocity or direction changes, it has to involve some acceleration. If the body were moving in a straight manner and also at a constant speed, acceleration would be not be involved. Which of the following constitutes a fat molecule?A. A single carbon, a single hydrogen and a single oxygen molecule B. 3 fatty acid molecules and a single glycerol molecule C. A single molecule of glycerol and 3 molecules of stearic acid D. 3 glycerol molecules and a single fatty acid molecule - B. 3 fatty acid molecules and a single glycerol molecule There are three organic acid molecules required in the formation of a fat molecule. This organic acid is commonly referred to as a fatty acid. These three molecules in combination with a single glycerol molecule can make up a single fat molecule. Identify the best answers to complete the sentence. "Enzymes are ______ which work best while at ______ pH or even temperature." A. Chemical substances, moderate B. Biological catalysts, optimum C. Organic catalysts, lowest D. Inorganic catalysts, maximum - B. Biological catalysts, optimum The best definition of a catalyst is a substance of a chemical nature that has the capacity to accelerate a reaction while not being spent or changed. As for enzymes, they are catalysts of a biological or organic nature, made of living cells, and they hasten various body reactions. Which of the following statements is true about the process of fermentation? A. It is an aerobic procedure whereby a solution of sugar is acted on by yeast and releases oxygen as well as alcohol B. It is an anaerobic procedure whereby a solution of sugar is acted on by yeast and releases carbon dioxide as well as alcohol C. It is an anaerobic procedure whereby a solution of protein is acted on by bacteria and produces carbon dioxide as well as alcoholD. It is respiration by tissue whereby carbohydrates are acted on by yeast and produces oxygen as well as alcohol - B. It is an anaerobic procedure whereby a solution of sugar is acted on by yeast and releases carbon dioxide as well as alcohol [Show More]
